Official Description
Epic Games Unreal Engine 226f through 436 allows remote attackers to cause a denial of service (CPU consumption or crash) and possibly execute arbitrary code via (1) a packet with a negative size value, which is treated as a large positive number during memory allocation, or (2) a negative size value in a package file.
Technical Analysis
CVE-2003-1432 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
